Thanks @marshallpierce. I've started a bit of development (not pushed yet). Staging for that work will be at https://github.com/posborne/rust-gpio-cdev

from rust-sysfs-gpio.

I found https://www.youtube.com/watch?v=76j3TIqTPTI&feature=youtu.be to be pretty helpful in understanding the new gpio interface.

gpio-cdev exists now so I will go ahead and close this.

Thanks for the heads up @samdolt, I believe we should be able to select the appropriate one at runtime, but this will require a bit more investigation into the specifics of how gpio-cdev works. Dropping sysfs support altogether will probably not be wise for some time (as plenty of systems still run kernels older than 4.4).
